Abstract: A method for fabricating a high density semiconductor integrated circuit device with a multilayer interconnect wiring structure is disclosed. This structure has a low-dielectric constant insulator film including an organic thin-film with its dielectric constant ranging from about 2.0 to about 2.4. To fabricate the multilayer wiring structure, a substrate with an inorganic film for use as an underlayer dielectric film is prepared. Then, apply plasma processing, such as plasma-assisted chemical vapor-phase growth, to a top surface of the inorganic underlayer dielectric film in environment that contains therein organic silane-based chemical compounds, thereby to form on the inorganic film surface a hydrophobic surface layer with a contact angle with water being 50° or higher. Next, form on the plasma-processed hydrophobic surface an organic film including a fluorinated aromatic carbon hydride polymer film.

Abstract: In a method for manufacturing a semiconductor device having a multi-layer insulating film, a first insulating film is formed as one layer of the multi-layer insulating film, and a plasma treatment is performed on the surface of the first insulating film in an ambient of helium and argon, containing 5 to 31% Ar. After the plasma treatment, a second insulating film, different from the first insulating film, is formed on the first insulating film as another layer of the multi-layer insulating film.

Abstract: A plasma thin-film forming apparatus comprises a vacuum vessel, a positive and a negative electrode disposed in the vacuum vessel so that the discharge surfaces may face each other at a required interval, an exhaust means for making a required vacuum condition in the interior of the vacuum vessel, a high-voltage impressing means for generating DC glow discharge by impressing high voltage between the positive and the negative electrode, and a gas-inducting means for supplying metal compound-including gas into the vacuum vessel. The gas-inducting means comprises a flexible holding member gastightly fitted to a sublimation chamber communicating with the vacuum vessel and having a hollow portion therein and a glass container inserted in the hollow portion of the holding member and enclosing a predetermined quantity of crysterized osmium tetraoxide therein. The exhaust means is provided with a material gas-adsorbing means in the exhaust port.
